Dialup error (different language distribution)

[padluke]

Hello, please advice.
In Windows 7 Pro x64 and x86, CZECH distribution, I have connected a USB modem. Drivers are fine, everything in the system is ok, but when I want to dial a number to get Error 633, Rasdial not work, still error 633. When the connection I use AT commands (putty), everything works fine.
I did a test and I found that Windows 7 x64, x86 English or German distribution, everything works fine without any errors. RasDial works fine.
Can anyone advise me where there may be a problem?
thank you
P.

Check if "Remote Access Auto Connection Manager" and "Remote Access Connection Manager" services are set to manual. And try starting them.

Is your Windows up-to-date? SP1 and all other updates?

 

[padluke]

Checked.
All services are set to manual and they are started.
All updates are installed.
Apparently unsolvable problem :-(

Does it work in Safe Mode with Networking?
A different user account? http://www.sevenforums.com/tutorials/181024-user-account-create.html

Mostly out of ideas, any 3rd party firewall on Czech OSs?
